REVERSING AND SPEED-REGULATING DEVICE FOR MUSICAL-INSTRUMENT CONTROLLING-SHEETS.

SPECIFICATION forming part of Letters Patent N 0. 764,352, dated July 5, 1904.

Application filed January 9, 1904.

T0 11]? wit/mt it may concern:

Be it known that we, WILLIAM F. CooPER, J r., and HERBERT E. SHARrs, both citizens of the United States, and both residing at Chicago,county of Cook, and State of Illinois,have invented new and useful Improvements in Reversing and Speed-Regulating Devices for Musical-Instrument Controlling Sheets, of which the following is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

This invention relates to motors for operating the controlling-sheet of automatic musical instruments and to means for regulating the speed and reversing the action.

It consists in the features of construction set out in the claims.

In the drawings, Figure l is a plan view of a motor having the regulating and reversing devices constituting our invention, same being shown in connection with the take-up and rewinding rolls of the player, the parts being shown in positionof rest. Fig. 2 is a plan view of the same parts, the motor-train being shown only in outline, the adjusting parts being shown in full line in position for operating the take-up or winding roll at slow speed and in dotted lines at two positions, the first that for operating the take-up roll at high speed and the second position for disconnecting the take-up roll without interrupting or'modifying the speed of the motor.

The motor shown in the drawings is constructed according to our Patent No. 697 ,7 54:,

dated April 15, 1902, and need not be here described beyond calling attention to the fact Serial No. 188,320. (No model.)

having a pinion 6 engaging a gear 7 on the take-up or winding roll B; a shaft 8, telescoping at one end and obtaining bearing thereby within the sleeve-shaft 5 and journaled at the other end in a bracket 9; a sprocket-wheel 10, fast on the shaft a; a sprocket-wheel 11, loose on the shaft 8 and having its hub provided with a groove 11, which is engaged by a fixed finger 12 on the bracket 9 for holding the sprocket-wheel 11 in position against lateral displacement.

On the end of the sleeve-shaft 5 opposite that which carries the pinion 6 said shaft has a clutch element 13, and the shaft 8 is adapted to be thrust back and forth through its hearing in the bracket 9 and in the sleeve-shaft 5, and for the purpose of such movement it has a clutch-collar 14 fast on it, provided at one end with a projection 14 for engaging the corresponding projection 11" on the end facing the clutch-collar of thehub of the sprocketwheel 11 and at the other end a corresponding projection 14 for engaging the clutch-collar. 13 on the sleeve-shaft the lever 15, pivoted on the base-board 16, on which the entire structure is mounted, having a linger 15 engaging a peripheral slot in the clutch-collar 1 for moving the shaft longitudinally back and forth as the lever is, rocked, and thereby carrying the clutch into engagement either with the sleeve-shaft 5 for rotating the pin-.

ion 6, gear 7, and take-up roll B or into ongagement with the sprocket-wheel 11 for rotating by means of the chain 1O the sprocketwheel 10, shaft 4, and the rewinding-roll.

At the end of the shaft 8 outside the bracket 9 said shaft carries rigidly the sprocket-wheel 17, connected by a chain 18 with the sprocketwheel 19 on the end of the final shaft of the train, which is mounted in the motor-frame C for deriving from the motor the power for brake-pad 21 for contact with. the governordisk/3'. The rear end of the lever 20 is connected by an extensible link 22 22 with the lever 23, which is fulcrumed on the base-board 16, said connection being made directly to an adjustable plate24 on said lever 23, so that the distance of the pivotal connection of the link 22 22 from the fulcrum of the lever 23 may be varied to vary the maximum speed of the governor. For such adjustmentof the plate 24 it has two slots 24 24, through which screws 24 24 pass to secure it to the lever 23. The lever 15 has an arm 15 projecting in general toward the fulcrum of the lever 23, and said lever 23 has a spring-finger 23, which extends in position to engage the arm 15 when the lever 23 is swung about its pivot to the left that is, in direction for causing the link 22 22, operating on the lever 20, to carry the friction-pads of said lever away from the governor-disk to permit acceleration of the latter. The collision or engagement of the springfinger 23 with the lever-arm 15 in the movement described operates the lever 15 in direction for disengaging the clutch 14 from'the sprocket-wheel 11 and engaging it with the clutch-collar 13 on the end of the sleeve-shaft 5 to rotate the pinion 6, gear 7 and winding-roll B. The spring-finger 23 of the lever 23 runs off the end of the arm 15 of the lever 15 after operating said lever 15 sufiiciently to effect the engagement of the clutch 14 with the clutch 13. On the end of the sleeve-shaft 5 and during a further range of movement of the lever 23 in the same direction as that for causing said clutch engagement it will be noticed that the friction-brake 2 is being carried in direction for permitting acceleration of the motor. For operating the lever 23 we provide alever 25, fulcrumed on the under side of the baseboard 16, having a finger 25 projecting up from a slot 16 in the base-board and connected by a link 26 with the lever 23, so that the operator by swinging the finger 25 back and forth in the slot 16 operates the lever in either direction to any desired extent within the range of construction. an ofl'set or arm 27 which is adjustable longitudinally on the link and projects therefrom in position to encounter an abutment 15 on the lever 15 at a position of said lever corresponding to the maximum speed of the motor, said maximum being thus determined by the adjustment of said offset or arm 27 on the link. The engagement of the arm .27 with the lever 15 being at the opposite side of the fulcrum of said lever from that at which the finger 23 of the lever 23 engages the lever 15, the movement of the latter lever caused by the encounter therewith subsequent to the movement of the arm 27 is in the reverse direction from that which said lever 15 in the earlier part of the movement of the stop-finger 25 derives from the lever encounter of the spring-finger 23, and in such reverse movement the finger15, engaged with the clutch The link 26 has.

14, moves said clutch out of engagement with the clutch 13 and into engagement with the gear 11, causing the winding-roll to come to rest and the rewinding-roll to be actuated. The movement of the lever 23 for such reversal of the clutch connections and shifting the motive power from the winding to the rewinding roll carries the governor-brake 2 still farther in the direction for accelerating the speed of the motor and permits the latter to run at the limit of its speed, or practically without control by the brake while operating the rewinding-roll, thus giving said roll the highest speed within the power of the motor for rewinding the controlling-sheet as quickly as possible. The finger 23 is made elastic for the purpose of permitting it to yield as the lever 15 is operated by the arm 27 of the link 26 for swinging the lever 15 in the direction for disengaging the winding-roll train and engaging the rewinding roll train. When in resetting the lever 25 to rest position by means of the stop-finger 25 the end ofthe spring-finger 23 will run off the end of the arm 15 of the lever 15 and snap back to its original position behind said arm ready for engagement of its end therewith. as before. See, in Fig. 2, dotted-line position of said finger just ready to run off the end of the arm 15 and full line position after it has snapped back to original rest position.

In order to render it possible to arrest the action of thewinding-roll without stopping the motor or the main train operated by it and reengage the winding-roll of the train at will, so that the rotation of the latter may be resumed at substantially the speed which it had before disconnection, (such action being desirable in playing to preserve the tempo notwithstanding such an interruption,) the distance between the facing ends of the two elements which are engaged by the clutch 14--to wit, the hub of the sprocket-wheel 11 and the clutch 13 on the end of the sleeveshaft 5is such as to allow said clutch 14 to stand intermediate the two without engagement with either,and the lever 15 for operating said clutch is connected by a link 28 with a stop-lever 29, fulcrumed on the foundationboard 16 and having a stop-finger 29 for opcrating it protruding through the slot of the- I this position the operator will cause either the winding-roll orthe rewinding-roll, whichever may be in operation at the time, to come to rest while the motor continues its action. This operation, if performed while the winding-roll is running, merely takes thc abutment 15 of the lever 15 away from the arm 27 on the link 26, and although if performed when the rewinding-roll is in action the direction of movement of the abutment 15 is such upon its encounter with the arm 27 as to thrust the link 26 and swing the lever 23 in direction for retarding the motor such retardment will only reduce its speed to the maximum winding speed, and in the instances in which it is desired to interrupt the rewinding in this manner the mere retardment of the motor to this extent is not objectionable.

The link 22 22 is rendered extensible by the slotted connection of the two elements 22 22, by means of the clamping-bolt 22 and such extensibility facilitates the correct ad justment of the parts in mounting them upon the base-board 16, in respect to which absolute uniformity and consequent accuracy of adjustment for the governor would be difficult to obtain, and it is. rendered unnecessary by said adjustability of the link and also further by the adjustability of the plate 24 on the lever 23.
